Rosylyn, You are wrong. Catfish are indeed bottom feeders but what you fail to understand is that there is in fact a very live ecosystem at the bottom. Cat fish are omnivorous(eating both plants and animals). These foods include aquatic plants and seeds, fish, mollusks, insects and their larvae, and crustaceans.
